Acetaminophen toxicity after repeated administration of amounts that only moderately exceed recommended doses, is being increasingly reported in alcoholic or fasting adults. Pediatric experience with this pattern of acetaminophen toxicity is sparse.

We present 2 children who developed severe hepatic damage, with renal insufficiency as well in 1, after 15-20 mg/kg of acetaminophen, given at 4-hour intervals for 3-4 days during an intercurrent febrile illness. When given in doses as low as 20 mg/kg at frequent intervals for a number of days, the drug puts children who are vomiting or have sharply reduced caloric intakes at increased risk for severe toxicity.

Increased caution and awareness of the toxic effects of acetaminophen are needed, and it should be dispensed with appropriate package-label warnings.

Therapeutic injection of botulin toxin is well-recognized for reducing tonus in local dystonia. However, its efficacy in reducing spasticity in spinal cord injuries is still unproven. 4 men and 1 woman (mean age 39 years, range 20-56) with spinal cord injury and debilitating spasticity, and no response to standard treatment for spasticity received injections of botulin, 200-300 U, into 4-8 points in their legs to block muscle-nerve synapses.

In all 5 tonus was reduced in the area of the block, while in some it was also reduced in more distal muscles. In 1 there was reduced tonus in both the injected and contralateral leg. The therapeutic effect on tonus persisted for 3 months. In spite of objective improvement in tonus in all 5, only 3 felt subjective improvement, but in none was there improvement on standard functional scaling.

We found injection of botulin toxin effective in reducing tonus in the spinal cord-injured, and to some extent in improving subjective feeling of well-being in some of them. Obective measurement might show functional improvement after larger doses of toxin injected into more muscles. This might be necessary because the muscle mass of the legs is large and the intensity of involuntary contraction is especially high in these patients.

It is clear to experts in the health care industry that with regard to medical decision-making, considering costs of medical devices is not a good index, but it is highly important to include medical aspects. This approach guarantees an advance and an appropriate method.

We present a cost-effectiveness analysis to target the optimal strategy of how to use medical diagnostic devices in cases of knee injuries. Today, one of the more common medical emergency referrals seen worldwide is in the area of orthopedics, knee injuries in particular. They can harm soft tissue, bone tissue, or both simultaneously. The diagnosis of soft tissue injury is difficult at best. Among the devices helping the clinician make an accurate diagnosis are MRI and ultrasound (US).

We conclude that US is superior to MRI in this condition. This is especially true when the orthopedic examination leads to the suggestion of arthroscopy. The results were not modified, and a sensitive study of the parameters that influence the decision- making process was undertaken. Decision-makers should not consider medical outcome alone, but should take into account the costs. A clinical study should validate the assumption on which this study was based.

Gyrate atrophy of the choroid and retina is a rare degenerative disease, characterized biochemically by a marked increase in blood ornithine levels, due to deficiency of ornithine S-amino transferase. 4 men aged 35, 36, 48 and 62 years are described with different stages of myopia, night blindness and loss of peripheral vision, which progressed to tunnel vision and partial blindness. Onset of the disease was at ages 3, 10 and 15 years, respectively, while in the 4th patient there was delayed expression starting at about age 50. Most had posterior subcapsular cataracts, and the ocular fundus exhibited demarcated circular areas of chorioretinal degeneration. So far the only patients described in Israel have been of Iraqui origin. Our fourth patient originated from Istanbul, and he may represent a hitherto undescribed variant with a much delayed expression of the disease.

Sacrospinous ligament fixation is a well-known method for correction of vaginal vault prolapse. The procedure is primarily indicated after hysterectomy and as a prophylactic measure for total uterine prolapse.

8 women with post-hysterectomy vaginal vault prolapse aged 48-72 years, were referred 1-25 years following primary surgery. Sacrospinous ligament fixation was elected to enable simultaneous correction of cystocele and rectocele, and to preserve sexual function. All operations were completed without significant complications.

In 6 of the 8 patients located for long-term interview, 1 reported mild bulging of the introitus, another mild urinary stress incontinence, urgency and frequency and 1 reported frequency only. Sexual function in 4 was without complaints. Defecation in all patients was normal.
We conclude that this operation is safe and effective. We encourage gynecologic surgeons to consult an experienced tutor prior to performing this procedure, as this type of surgery is quite dangerous and many gynecologists are not familiar enough with it.

Scrofula (mycobacterial cervical lymphadenitis) has been well-known for thousands of years. Atypical mycobacteria were first categorized by Timpe and Runyon in 1954. Treatment has varied over the centuries, from exclusion therapy in ancient Greece, through digitalis, iodide, chemotherapy, and surgical excision. The varied differential diagnosis and consequent diagnostic and therapeutic challenges make reassessment of this almost forgotten disease necessary.

21 patients with typical mycobacterial cervical lymphaden„itis seen in over the past 5 years were reviewed. Age distribution ranged from 1-14 years, with peak incidence at 4 years; 9 were boys and 12 girls. Most presented with nontender, palpable neck masses and minimal constitutional complaints. Adenopathy was unilateral in all cases but 2. Mycobacterium avium-intracellulare and M. fortuitum were the main causative organisms. All underwent excision of the affected nodes. Long-term follow-up has been uneventful, except for 1 case of local recurrence requiring re-excision.

This study emphasizes the marked variability in the clinical presentation of scrofula in children, stressing the importance of the differential diagnosis between tuberculous and atypical mycobacterial cervical lymphadenitis. The treatment of choice for the latter is complete excision of the affected nodes. Other treatment is followed by recurrence and unnecessary complications and should be avoided.

Massive splenomegaly is defined as a spleen weighing about 10 times normal weight. We describe a 36-year-old man who had huge splenomegaly and secondary pancytopenia simulating malignant lymphoma for about 3 months. Splenectomy was necessary because of the suspicion of hematologic malignancy, especially isolated lymphoma of the spleen, and pain and mechanical abdominal disturbances.

On operation, the spleen was 25 cm long and weighed 250 g. There was florid, reactive follicular lymphoid hyperplasia. Immunohistochemical staining with CD-20(L26), CD-45Ro(UCHL), bcl-2 oncoprotein (Dakopatts), EBV (anti-EBV mol weight 60 KD, Dakopatts) was consistent with reaction to EBV infection and not with follicular lymphoma. Lack of PCR amplification using DNA extracted from paraffin-embedded splenic tissue indicated absence of a monoclonal B cell population carrying rearranged immunoglobulin genes. The lymphocytic population was proven polyclonal by the negative results of PCR for the bcl-2 gene rearrangement. EBV seroconversion from high titer antibodies of anti-EBV-VCA-IgM to negative, and from negative EBNA to positive was consistent with an apparent primary EBV infection.

We have not found on computerized search a previous report of reactive follicular splenic hyperplasia to EBV infection causing huge splenomegaly, with or without EBV-induced infectious mononucleosis.

Adult-onset Still's disease (AOSD) is characterized by a spiking fever and diverse clinical findings; the diagnosis is often delayed for months or even years. The only positive laboratory finding is neutrophilic leukocytosis. Since 1987, the diagnostic importance of elevated serum ferritin levels has been discussed in numerous papers, but is not yet among the diagnostic criteria for AOSD. We describe a case in which the finding of extreme hyperferritinemia enabled prompt diagnosis and treatment.

Familial hemiplegic migraine is a rare autosomal, dominant, migraine subtype. It is characterized by acute episodes of hemiplegia and hemisensory deficits, and other neurological abnormalities occurring either before or together with severe headache, nausea and vomiting; episodes last several hours and then spontaneously subside. Intervals between episodes are relatively prolonged. Unless there is a relevant family history suggesting this syndrome, the diagnosis is usually delayed. Recently the gene for the syndrome was identified on chromosome 19. We report 3 boys and 1 girl, 11-15 years old with hemiplegic migraine.

It is well known that maelderly patients are referred to nursing homes because of "functional decline" without being thoroughly in. We studied 9 elderly patients, all referred to hospital due to functional decline and diagnosed as follows: spinal stenosis - 2 cases, depression - 3, thyrotoxicosis -1, Parkinson -1, polypharmacy and congestive heart failure -1 patient each. Proper diagnosis and appropriate treatment prevent unnecessary hospitalization in nursing homes. Our study is meant to draw attention to this crucial aspect of geriatric medicine.

Pediatric care in the community is gradually replacing traditional care in hospitals. Despite that, research activity in the community setting is minimal due to objective difficulties. These are mainly constraints of time, office work and lack of research-supporting logistics. In the past decade, throughout the world, primary physicians interested in research have grouped together and formed research networks. The aim of such networks is to support and promote research in the community.

An Israel Pediatric Research in Office-Setting network (IPROS) was established 2 years ago by the Israel Ambulatory Pediatric Association (IAPA). Today, there are over 140 pediatricians listed in IPROS, representing the heterogeneous composition of pediatricians in Israel. The network's policy is defined by a joint steering committee. The committee is composed of IAPA representatives, senior network members and Schneider Hospital senior investigators. The research subjects are diverse, and represent common practical issues.

Effective intra-net communication is vital to the existence of the network, and is accomplished by 3 modalities: 1) semiannual updates by mail, 2) e-mail, using an electronic mailing list to facilitate connection between members, 3) semi-annual meetings. Research budgets are derived from public sources like the Ministry of Health and IAPA, and private sources such as pharmaceutical companies. The administration of the network is supported by Schneider Children's Medical Center, and financed by IAPA.

Nephron-Sparing Surgery - Initial Experience with 50 Patients

Urology Dept., Bnai Zion Medical Center, Haifa

During recent years the use of the new imaging techniques, ultrasonography and computerized tomography, has increased. The accessibility to these methods has changed the pattern of detection of renal lesions. Over 90% of renal masses are now discovered incidentally, while investigating nonurological symptoms. Therefor, most lesions are discovered in their early stages.

The gold-standard procedure for removing renal masses is radical nephrectomy, which ensures complete removal of an organ-confined lesion, but involves loss of functional tissue. This might be critical in patients with a single kidney, or reduced nephron function. There are several diseases characterized by multiple renal lesions, such as Von Hippel-Lindau and tuberous sclerosis in which radical treatment may lead to chronic dialysis in young patients.

Nephron-sparing surgery was developed in order to preserve as much functional tissue as possible while removing safely any suspicious renal lesion. This new technique, not involving radical surgery, should be evaluated in cases of renal tumors for its ability to achieve the same cancer cures rates. We present our experience with our first 50 patients who underwent nephron-sparing surgery for removal of renal lesions.

Sudden low back pain is common in elderly women. It causes physical and mental stress, and results in deterioration of functional movement and in activities of daily living. Awareness of possible sacral insufficiency fracture is important; they may be demonstrated by imaging modalities, mainly radionuclide bone scan. Prognosis is good and accurate diagnosis serves to exclude malignancy and relieve fear of chronic pain and disability. We describe 4 women, aged 84, 82, 71 and 77 who illustrating the clinical and imaging findings of this disorder.
